The only reason I want a callback is to do this:

while (TRUE)
 {
   gpointer p;

   sleep();
   
   p = g_malloc_try();
   if (p)
     return p;
}

(perhaps with a max number of tries for safety)

I want this specifically for gnome-session. If other apps do this it's
obviously very bad, but gnome-session should not be the app to fall
over if memory runs out.

Right, I remember we wanted the _try() functions.
